The TeV Connection

• Identified contacts with the major Cerenkov
  telescope groups
• H.E.S.S. Wagner, Puehlhofer
• Magic de Angelis
• VERITAS Krawczynski, Ong
• CANGAROO Kubo
• Met with VERITAS group in Nov. 2004., plus other
  meetings.
• Watched the exciting results come in from
  H.E.S.S.
• Julie McEnery has started a discussion group for
  LAT-TeV interests. Their Confluence Web page is
• http//confluence.slac.stanford.edu/display
  /GLAMCOG/TheTeVConnection

Essential Prioritized List of MW Needs

• Why? Because any multiwavelength effort involves
  some resources time, money, people, planning.
• A challenge for each of the LAT science groups is
  to help define these MW priorities.
• Assignment each science group provide a
  prioritized list of MW needs, including
  justification, specific examples, and some
  estimate of what resources LAT will have to
  provide. Goal end of September.
• Corollary we all need to explore ways to tap
  other resources. Possibilities NSFs Major
  Research Instrumentation Program or Program for
  Research and Education with Small Telescopes.
  The Italian government has provided some MW
  support. Perhaps approach the Astronomy and
  Astrophysics Advisory Committee.

Need 2 Identification of MW Facilities for LAT

• Why? MW planning depends on having contacts and
  agreements in place. MW efforts are needed before
  launch, as well as monitoring, follow-up,
  contemporaneous, and simultaneous observations
  during the mission.
• Assignment each science group start collecting
  information about available MW facilities, using
  the spreadsheet model distributed last weekend.
  Information includes science driver, wavelength
  information, and both LAT and facility contact.
• This spreadsheet will be available to the
  collaboration as a resource. It will be posted
  at the MW Confluence Web site

Need 3 Expand the MW Coordination Group

• Why? MW planning cuts across specific scientific
  groups. All science groups need to be represented
  on the MW group.
• Assignment each science group propose new
  members for the MW Coordination Group.

Need 4 Build on Existing MW Programs

• Why? We do not need to re-invent MW campaigns. A
  few examples
• Swift and the Gamma Ray Burst community make an
  excellent example of a working program.
• Our AGILE colleagues have some MW agreements in
  place.
• The Global Telescope Network and Whole Earth
  Blazar Telescope are helping coordinate MW
  efforts.
• The MW Coordinating Group needs to learn from and
  work with existing programs.

SUMMARY

• GLAST science will be maximized by MW studies
  carried out cooperatively between the instrument
  teams and the user community. In order to move
  beyond the report from last year, these steps are
  crucial
• Construct a prioritized, science-driven list of
  MW needs and the costs associated with them.
• Identify available MW facilities and contacts to
  help meet the science needs.
• Expand the MW Coordinating Group
• Build on/learn from existing MW programs
